Colour-changing nail polishes are a fun and unique way to express yourself. These polishes are technically known as thermochromic, which means they change colour when experiencing changes in temperature. They contain special pigments that react to heat and cold, resulting in a colour shift. This effect is achieved through the use of 'leuco dye', which comes in two forms: clear or colourless. When heat is applied, the dye transitions between these two states, creating a visible colour change on your nails. The polishes can shift between multiple colours, providing a magical and captivating experience for those who enjoy experimenting with their nail art.

The science behind colour-changing nail polish
Colour-changing nail polishes, also known as thermal polishes, are a unique blend of heat-reactive pigments. These polishes contain a special pigment called 'leuco dye', derived from the Greek word 'leuco', meaning white. The dye exists in two forms: clear and colourless, and it transitions between the two states when exposed to changes in temperature. This transition results in the nail polish changing colours.
The colour-changing property of these polishes is not influenced by the base or top coat but is dependent on temperature fluctuations. The polish changes colour based on body temperature and the surrounding environmental conditions. For instance, if your hands are cold, the polish will display one colour, and as your hands warm up, the pigments will shift, causing the polish to change to a different colour. This can result in an ombre effect, with some nails or parts of nails displaying one colour and others, a different shade.
The temperature-sensitive nature of the nail polish means that it can be influenced by various factors, such as hot or cold water, air temperature, or even your body temperature. This makes the colour-changing effect quite dynamic and unpredictable, adding an element of surprise and fun to your manicure. The length of your nails can also impact the colour contrast, with longer nails providing a more pronounced colour difference between the warm nail bed and the cooler tip.
In addition to thermal polishes, there are also photochromatic nail polishes that react to sunlight or UV light exposure. These polishes contain dyes that absorb specific wavelengths of light, causing the colour to darken when exposed to UV rays. When removed from sunlight or UV light, the polish gradually returns to its original shade.

How to apply colour-changing gel nail polish
Colour-changing gel nail polish is a fun way to get the most out of your chosen shades. The polish changes colour in response to heat and cold, thanks to the presence of leuco dye. This dye comes in two forms: clear and colourless. The shift between these two forms occurs when heat is applied.
- Start by applying a base coat to clean, bare nails. Allow this to dry completely. This base coat will prevent your nails from staining.
- Next, apply the colour-changing gel nail polish. Smooth on a single layer to each nail and let it dry.
- Once the first layer is dry, go back and apply a second layer of polish.
- After the second layer has dried, use a cotton swab soaked in nail polish remover to wipe away any stray polish on your fingers.
- Finally, apply a top coat to protect your nails from chipping and to give them a glossy finish.
Your colour-changing gel manicure is now complete! You can expect it to last the same amount of time as any regular manicure or acrylic set. Just remember, due to its colour-changing properties, this type of nail polish has a shorter shelf life than regular nail polish.

The different types of colour-changing nail polish
There are several types of colour-changing nail polishes, each with its unique characteristics and colour-changing mechanism. Here is a detailed overview of the different types:
Thermal Nail Polish
Thermal nail polishes, also known as thermochromic nail polishes, are one of the most popular types of colour-changing nail polish. These polishes change colour in response to temperature variations. They contain heat-reactive pigments and leuco dyes, which allow them to switch between different colours when exposed to heat or cold. For example, a thermal nail polish might appear in its "'hot'" colour during summer and change when exposed to a cold environment, such as washing your hands with cold water. Conversely, during winter, it will display its "cold" colour and transition to its "hot" colour when exposed to heat. The temperature sensitivity of these polishes can vary, with some creating an ombre effect due to the difference in temperature across your fingers.
Photochromatic Nail Polish
Photochromatic nail polishes, also known as solar nail polishes, react to sunlight or UV light exposure. They contain tiny crystals that become chemically excited by UV radiation, causing them to change colour. When removed from sunlight or UV light, the crystals gradually calm down and return to their original, invisible state. This process is reversible, so if kept away from UV light or sunlight for an extended period, the polish will revert to its original shade. Photochromatic polishes can change from being colourless to a colour or transform from one colour to another.
Multi-Chrome Nail Polish
Multi-chrome nail polishes, also known as duo-chrome or chameleon polishes, exhibit colour-changing properties through the use of reflective pigments. These pigments settle into layers on your nail, and when light hits the nail surface from different angles, it reflects off distinct layers, resulting in the appearance of different colours. The colour transition in multi-chrome polishes does not depend on temperature or sunlight but rather on the angle at which light hits the nail surface.
Magnetic Nail Polish
Magnetic nail polishes are another type of colour-changing polish that creates various designs and shapes when a magnet is applied while the polish is still wet. This type of polish allows you to create unique patterns and effects on your nails by manipulating the magnetic particles within the polish.
Holographic Nail Polish
Holographic nail polishes are somewhat controversial as colour-changing polishes, but certain ultra-holographic polishes are considered to meet the criteria. Unlike mirror-like reflective polishes, holographic polishes are refractive like a prism. They take normal white light and break it down into tiny rainbows, creating a colour-changing effect.

How to fix colour-changing gel nail polish
Colour-changing, or thermal, nail polishes are technically known as thermochromic, which means they change colour ("chromic") when they experience changes in temperature ("thermo"). The polish contains a dye called leuco dye, which comes from the Greek word "leuco", meaning "white". This dye exists in two forms: clear or colourless, and the change between the two occurs when heat is applied.
- Store your nail polish in a cool, dry place when not in use. Exposure to sunlight can cause the gel to go bad and become discoloured.
- Seal the bottle after every use. Knowing how to swirl nail polish is also important to prevent air bubbles from forming in the polish.
- Wash your hands immediately after using anything that could stain your nails, such as cooking ingredients or cleaning agents.
- Avoid overexposure to UV light. This includes spending a lot of time in the sun or using self-tanners.
- Choose higher-quality gels. Lower-quality gels are more prone to discolouration and brittleness.
If you are still having issues with colour-changing gel nail polish, consider contacting a nail technician or cosmetologist for further advice.
